AI Security Review
scanned 6d ago · by lpm-firewall-aiThe preinstall hook only checks the Node version. The runtime network behavior is disclosed telemetry with an opt-out, while AlphaXiv credentials are sent to AlphaXiv’s own authentication endpoint for the requested status check.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The Node version check runs during installation; telemetry runs when the CLI starts; AlphaXiv authentication checks run with the alpha status command.
Impact
No malicious impact identified.
Mechanism
The install hook checks the Node version. Runtime telemetry is disclosed and opt-out capable; AlphaXiv sends its bearer token to its own userinfo endpoint for authentication status.
AI rationale
The preinstall hook only checks the Node version. The runtime network behavior is disclosed telemetry with an opt-out, while AlphaXiv credentials are sent to AlphaXiv’s own authentication endpoint for the requested status check.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The preinstall hook only runs a Node version check and exits if the version is unsupported.
- Runtime usage telemetry is disclosed, uses an anonymous random ID, and can be disabled with FEYNMAN_TELEMETRY=off.
- AlphaXiv credentials go to AlphaXiv’s own userinfo endpoint when the alpha status command is used.
Evidence against
- Runtime telemetry is enabled by default and sends usage and error information to PostHog.
